NEMATODES IN CABNATION SOU.. 



Do you know of anything that can 

 be mixed with the soil, either in the 

 compost pile or on the benches, to 

 kill nematodes? The soil in which our 

 carnations are growing is badly infested 

 with them and the trouble is cutting 

 our carnation crop in half. 



H. B.— Ala. 



The Louisiana state experiment sta- 

 tion has done a great deal of work in 

 the control of this pest and can prob- 

 ably advise you better than anyone 

 else. Address it at Baton Rouge, La. 

 This trouble seems more prevalent in 

 the southern states, though I am not 

 sure that it is entirely confined to that 

 section. All the cases that have come 

 to my notice have been below the Ma- 

 son and Dixon line. A. F. J. B. 



SPACE FOB CARNATIONS. 



How large a space would 5,000 car- 

 nation plants take up and how large 

 a greenhouse would be required for that 

 number? How many blooms would each 

 plant produce and what would the re- 

 ceipts and the clear profit be? 



M. B.— Can. 



It would reouire three benches 

 5x200 to hold 5,000 carnation plants, 

 setting seven plants across the bench 

 and spacing the rows ten inches apart. 

 These benches would hold 4,682 plants, 

 to be exact. A fair average of blooms 

 per plant would be fifteen, depending 

 entirely on your success as a grower. 

 Their market value would depend on 

 prevailing prices in your market and 

 your profits would depend on the quality 

 of your product and your economy in 

 producing it. My advice to you would 

 be to look about you and see how 

 others are faring. If other growers 

 are growing carnations and selling them 

 profitably in your market, you can prob- 

 ably do the same. A. F. J. B. 



CARNATION TEMPERATURE. 



"We are sending you two branches 

 from our carnation plants, which seem 

 to be affected with some disease. The 

 shoots, you will notice, cramp and curl. 

 Can the plants have suffered from cold? 

 Our night temperature runs from 42 to 

 55 degrees, but it might have fallen 

 below 42. 



In an adjacent service building we 

 keep an automobile truck. Could the 

 gas from the exhaust cause the trouble? 



R. G.— HI. 



A range of 42 to 55 degrees is cer- 

 tainly no kind of temperature for car- 

 nations. If you cannot control it any 

 better than that, you can expect but 

 little success in your carnation grow- 

 ing. A range of 48 to 52 is enough 

 latitude for anyone. 



If those burnt gas fumes enter the 



greenhouse, they would most certainly 

 affect your crop; the plants would take 

 on a stunted appearance and the blooms 

 would fail to open properly. 



A. F. J. B. 



eontains considerable alkali, the effect 

 of which is to a large extent overcome 

 by the use of rain water. However, a 

 strong-growing variety is liable to show 

 the effect of it at this time of year, 

 when during dark weather water is 

 kept off and the plants are allowed to 

 get a little too dry. The strongest 

 plants and those along the south edge of 

 the benches will usually show the ef- 

 fect first. If the plants affected by it 

 are kept a little wetter, they will usual- 

 ly outgrow it. W. J. K. 



ALKAU IN ROSE SOIL. 



I am sending you under separate cover 

 some samples of Ophelia rose leaves that 

 are affected with something that has 

 appeared here and there on the plants, 

 which otherwise are growing excellent- 

 ly. There were about two weeks of 

 dark, cloudy weather and since that 

 spell I have noticed the leaves turning 

 this way. I use only rain water to water 

 these plants. Is there anything you can 

 tell me to do to prevent this spreading? 

 I am growing Hoosier Beauty, Ophelia, 

 Columbia and Premier and at this time 

 Ophelia is the only one affected and 

 of it only a few plants, perhaps two 

 dozen in all. B. F. S.— S. D. 



LETTUCE LEAVES BROWNED. 



I am sending you a few lettuce 

 leaves, which have turned brown and 

 withered. This trouble has completely 

 ruined my crop. The crop is nearly 

 ready for market and was looking well 

 until all the plants began to go brown 

 like this; they seem to wither and die. 

 Can you tell me the cause of the trou- 

 ble? W. J. L.— N. Y. 



Judging from the appearance of the 

 sample leaves, I believe that the soil 



The scorching on the ends of the 

 foliage is usually due to extremely 

 bright weather following several sunless 

 days and the damage is always the 

 worst where the plants are run at a low 

 temperature, say 40 to 42 degrees at 

 night. It is less marked when a mini- 

 mum of 45 to 48 degrees is maintained, 

 with a rise to 55 degrees on dark days. 

 Careful ventilation is necessary; if air 

 is neglected a little too long on a bright 

 morning, serious damage will be done. 



Decatnr, lU. — Daut Bros, have ob- 

 tained a permit to build a new green- 

 house to cost $19,000. 



Wilmington, Del. — The Riverside 

 Greenhouse Co., with a capital of $200,- 

 000, was recently incorporated. 



East Palestine, O. — J. N. Spanabel & 

 Sons are erecting three short-span

 They are to bo 14%x225 feet. 



Douglas, Ariz. — M. C. Elliott, who 

 formerly was connected with the La 

 JoUa Floral Gardens, La JoUa, Cal., 

 has started in business at 558 Tenth

Handley, Tex. — The Woods Floral 

 Co., of which J. T. Woods is the pro- 

 prietor, has bought out the business of

 000 feet of glass and six acres of land. 

 This company has discontinued its busi- 

 ness in Dallas, Tex. 



Birmingham, Ala. — The McVay Seed 

 & Floral Co., which succeeded the Mc- 

 Vay Seed Co., now deals in practically

 S. Mobley; secretary and treasurer, L. 

 E. Harris. 



Cleburne, Tex. — The Cleburne Floral

 tion of three new greenhouses, which 

 will give this firm about 15,000 feet of 

 glass. 



Norfolk, Va.— The Grandy Floral Co. 

 was the victim of robbery, February 9. 

 The thief was caught. He had about 

 $200 worth of florists' equipment at 

 his home. 



Miles City, Mont.— The Miles City 

 Greenhouses were incorporated recent- 

 ly by M. II. Wallace, J, L. Wallace and

Evanston, Wyo. — Louis B. Westheld- 

 er has extended his operations until 

 he now conducts the two largest flower

Marion, HI. — Mrs. Minnie Lilley Cope- 

 land, proprietor of the Marion Green-

 manager of the range, and will be de- 

 voted to carnations.
